Why creating FilingDocument records with `is_error == True`?

[esvhd]

Hi,

I noticed that when a FileDocument object is created, its is_error field is set to True if the document has content. Pls see line below.

openedgar/lexpredict_openedgar/openedgar/tasks.py

Line 89 in 1d1b8bc

filing_doc.is_error = len(document["content"]) > 0

Would someone be able to share some thoughts on why is_error is marked as True in this case? Presumably when a document has content, it is not an error?

Thanks.
